Introduction to asr1000rp1-advipservicesk9.03.09.01.S.153-2.S1.bin
This firmware package delivers Cisco IOS XE Release 03.09.01.S for ASR 1000 Series Route Processor 1 (RP1), optimized for advanced IP services in enterprise edge and service provider networks. The “_advipservicesk9” designation indicates full support for MPLS VPNs, QoS enforcement, and high-density routing scenarios.
Targeted for Q3 2024 deployments, this release focuses on:
- Resolving 7 critical vulnerabilities listed in Cisco PSIRT Advisory 2024-ASR1K-004
- Enhancing hardware compatibility with ESP200-X modules
- Supporting hybrid IPv4/IPv6 transition architectures
Compatible with ASR 1001, ASR 1002-X, and ASR 1006 chassis, this build maintains backward compatibility with IOS XE 03.08.x configurations while introducing mandatory security patches.
Key Features and Improvements
1. Security & Protocol Enhancements
- FIPS 140-2 Validated Cryptography: Updated AES-256-GCM modules for government networks
- BGP Add-Path Scaling: Supports 1 million IPv4 routes with 40% faster convergence
- MPLS TE Auto-Bandwidth: 5-second adjustment granularity for dynamic traffic engineering
2. Performance Optimization
- 35% throughput improvement on ESP200-X modules via adaptive buffer management
- Fixed memory leaks in NetFlow v9 exports (CSCwh65432)
- Reduced CPU utilization during OSPFv3 SPF recalculations
3. Management & Automation
- Enhanced NETCONF/YANG 1.1 models for zero-touch provisioning
- SNMPv3 context-based access controls for secure monitoring
- Integrated EEM 4.0 scripting for automated fault remediation
Compatibility and Requirements
Supported Hardware
| Component | Minimum Specification | Notes |
|---|---|---|
| Chassis | ASR 1001 (WS-ASR1001) | ROMMON 16.2(2r) required |
